TECHNICAL FIELD

The present disclosure relates to the field of communications and, forexample, relates to an uplink control receiving method, an uplinkcontrol sending method, a base station, a user equipment, and a storagemedium.

BACKGROUND

The new generation mobile communication system, i.e., New Radio (NR), isbeing researched and standardized, which is also one of currentpriorities of the 3rd Generation Partnership Project (3GPP).

In the currently determined NR system, three typical service types existin the future. The common services include: enhanced Mobile BroadBand(eMBB), Ultra-Reliable and Low Latency Communications (URLLC) andmassive Machine Type Communications (mMTC). These services havedifferent requirements for latency, coverage and reliability. Forexample, the eMBB mainly focuses on high peak transmission rate, has alow requirement on latency (no demand for low latency), and has a mediumrequirement on reliability. The URLLC focuses on low latency andhigh-reliability transmission, and is very demanding on latency. ThemMTC focuses on a large number of terminals, large connection densityand requires broader transmission coverage, while has little requirementon latency.

Some wireless data and control structures designed for the 5thgeneration wireless communication technology (5G) are described below.FIGS. 1 and 2 are structural diagrams of a transmission unit discussedin the early NR technology. As shown in FIG. 1 , it can be considered asone basic transmission unit, for example, one Transmission Time Interval(TTI) composed of multiple Orthogonal Frequency Division Multiplexing(OFDM) symbols, or one subframe composed of multiple TTIs. The downlinkcontrol is control type information related to downlink data, which issent by a base station to a user equipment (UE). The guard period (GP)is time for implementing transition between receiving or transmittingstates. The uplink data is data sent by the UE to the base station. Theuplink control is information sent by the UE to the base station, suchas downlink data receiving acknowledgement (ACK)/non-acknowledgement(NACK) feedback information, channel state information (CSI), ascheduling request and so on, which is information that the UE needs tosend to the base station except the uplink data. FIG. 2 shows a basictransmission unit for downlink data transmission, which, for example,contains downlink control, downlink data, a GP and uplink control. Thefunction of each part is the same as the corresponding part in FIG. 1 .

Such basic transmission units are allowed to be aggregated. That is,multiple basic units are connected in series to form a longertransmission unit for data transmission, and in-between transmissionunits may be data only and contain no control parts.

In one transmission unit, when uplink control is contained, the uplinkcontrol is considered to contain one OFDM symbol in the related art, andsuch uplink control is referred to as short format uplink control. Inorder to support time division multiplexing of uplink controls ofdifferent receiving ends (e.g., UEs) in one transmission unit, amechanism is also being considered to be introduced to indicate for theUE an OFDM symbol in which the UE's own uplink control is located. Thatis, multiple uplink controls will be included in one transmission unit,and each uplink control occupies one OFDM symbol.

If multiple uplink controls are included in one transmission unit andeach uplink control occupies one OFDM symbol, a receiving end or asending end can be simply implemented with the highest efficiency onlythrough the combination of the uplink control and the way of configuringthe location of a beam.

Possible problems existing when time division multiplexing of multipleuplink controls of different receiving ends exist in one transmissionunit will be analyzed below.

It is assumed (only for convenience of description, and the assumedscenario does exist) that in one transmission unit, there are tworeceiving ends, where the receiving end 1 needs to transmit uplink dataand uplink control, and the receiving end 2 only needs to transmituplink control. It is assumed that the receiving end 1 corresponds to abeam direction 1, the receiving end 2 corresponds to a beam direction 2,and a sending end (e.g. a base station) cannot receive the beamdirections 1 and 2 in one OFDM symbol at the same time (which may becaused due to various reasons, for example, the base station only hasone radio frequency link). It is assumed herein that each uplink controloccupies one OFDM symbol.

If a receiving end 1 transmits uplink data in the uplink data part ofthe transmission unit in the beam direction 1, in the transmission unit,the uplink control corresponding to the beam direction 2, i.e., theuplink control of the receiving end 2, is configured in an OFDM symbolafter and adjacent to the uplink data (i.e., configured in thepenultimate OFDM symbol), and the uplink control corresponding to thebeam direction 1 is configured in the last OFDM symbol. At this time,the processing of the receiving end 1 becomes complicated. The receivingend 1 herein transmits the uplink data until the antepenultimate OFDMsymbol, then the sending is suspended until the penultimate OFDM symbolends, and then continues to send the uplink control in the last OFDMsymbol. At this time, the uplink control of the receiving end 1, due toinsufficient adjustment of automatic gain control (AGC) of the receivingend and other reasons, may be subjected to decreased sending performance(after a device starts sending, a power amplifier level needs to climbup for stable sending), and a gap exists in the sending performed by thereceiving end 1 (e.g., the gap exists in the penultimate OFDM symbol),making the implementation of the receiving end 1 complicated. Theprocessing of the sending end (e.g., a base station) will also becomecomplicated due to the occurrence of the gap.

Therefore, in the related art, the configuration manner of locations ofOFDM symbols for uplink controls of receiving ends may cause complicatedprocessing.

When a beam direction of the uplink control is the same as a beamdirection used for transmitting uplink data in the transmission unit,the receiving end determines the OFDM symbol in which the uplink controlis located in the transmission unit as an OFDM symbol adjacent to anOFDM symbol transmitting uplink data in the transmission unit, or thereceiving end determines the OFDM symbol in which the uplink control islocated in the transmission unit as at least two continuous OFDM symbolsstarting from an OFDM symbol adjacent to an OFDM symbol transmittinguplink data in the transmission unit.

When multiple beam directions used for transmitting uplink data in thetransmission unit exist and a beam direction of the uplink control isthe same as at least one of beam directions used for transmitting uplinkdata in the transmission unit, the receiving end determines the OFDMsymbol in which the uplink control is located in the transmission unitas an OFDM symbol adjacent to an OFDM symbol transmitting uplink data inthe transmission unit, or the receiving end determines the OFDM symbolin which the uplink control is located in the transmission unit as atleast two continuous OFDM symbols starting from an OFDM symbol adjacentto an OFDM symbol transmitting uplink data in the transmission unit.

When a beam direction the same as at least one of beam directions usedfor transmitting uplink data in the transmission unit exists in PUCCHsof receiving ends of different beam directions, UCI with a beamdirection the same as at least one of beam directions transmitting theuplink data is carried in a PUCCH in an OFDM symbol immediately beforeor after an OFDM symbol transmitting uplink data in the transmissionunit, where the OFDM symbol determined by the receiving end, in whichthe uplink control is located in the transmission unit, is an OFDMsymbol adjacent to the OFDM symbol transmitting uplink data in thetransmission unit, or the OFDM symbol determined by the receiving end,in which the uplink control is located in the transmission unit, is atleast two continuous OFDM symbols starting from an OFDM symbol adjacentto the OFDM symbol transmitting uplink data in the transmission unit.

When multiple uplink controls located in different OFDM symbols exist inthe transmission unit and a beam direction of the uplink control is thesame as at least one of beams directions used for transmitting uplinkdata in the transmission unit, the receiving end determines the OFDMsymbol in which the uplink control is located in the transmission unitas an OFDM symbol adjacent to an OFDM symbol transmitting uplink data inthe transmission unit, or the receiving end determines the OFDM symbolin which the uplink control is located in the transmission unit as atleast two continuous OFDM symbols starting from an OFDM symbol adjacentto an OFDM symbol transmitting uplink data in the transmission unit.

When a beam direction of uplink data of the receiving end is differentfrom a beam direction of the uplink control of the receiving end, thereceiving end determines the OFDM symbol in which the uplink control islocated in the transmission unit as an OFDM symbol adjacent to an OFDMsymbol transmitting uplink data in the transmission unit, or thereceiving end determines the OFDM symbol in which the uplink control islocated in the transmission unit as at least two continuous OFDM symbolsstarting from an OFDM symbol adjacent to an OFDM symbol transmittinguplink data in the transmission unit.

In an embodiment, before the step 602, at least one of a physical layersignaling or a high-layer signaling is received. The physical layersignaling includes downlink control information. The high-layersignaling includes an RRC message. The high-layer signaling configures apreset location of uplink control in the transmission unit when thephysical layer signaling and the high-layer signaling are usedsimultaneously. The preset location includes an end location of thetransmission unit or a location before transmitting uplink data. Thephysical layer signaling configures an OFDM symbol transmitting theuplink control. The step 602 may include that: according to at least oneof the received physical layer signaling or high-layer signaling, thereceiving end determines the OFDM symbol in which the uplink control islocated in the transmission unit.

In an embodiment, the step 602 may include: when the receiving endtransmits uplink data in the transmission unit, automatically adjustingthe OFDM symbol in which the uplink control is located to be an OFDMsymbol adjacent to an OFDM symbol for transmitting uplink data in thetransmission unit, or automatically adjusting the OFDM symbol in whichthe uplink control is located to be at least two continuous OFDM symbolsstarting from an OFDM symbol adjacent to an OFDM symbol transmittinguplink data in the transmission unit, where the being continuousincludes: being continuous forward or being continuous backward.

In an embodiment, before the step 604, a beam direction used fortransmitting uplink control in the OFDM symbol in which the uplinkcontrol is located may further be determined; and the step 604 mayinclude: sending the uplink control using the determined beam directionin the determined OFDM symbol.

In an embodiment, the uplink control meets at least one of: the uplinkcontrol occupying at least one OFDM symbol; the uplink control beingconfigured to send ACK/NACK information, CSI, or beam directioninformation; the uplink control being located in an OFDM symbol at anend of the transmission unit; the uplink control being located in anOFDM symbol before the OFDM symbol transmitting uplink data in thetransmission unit; or the uplink control being an area for transmittinga PUCCH, or an area for transmitting UCI.

In an embodiment, the transmission unit may be a subframe, a slot, amini slot, etc., and the OFDM symbol may be other resource unit oftime-frequency resources, which is used for characterizing a resourcemagnitude.

An uplink control sending method is further provided in an embodiment.FIG. 7 is a flowchart two of the uplink control sending method accordingto the embodiment. As shown in FIG. 7 , the method includes stepsdescribed below.

In step 702, a beam direction used for transmitting an uplink control inan OFDM symbol in which the uplink control is located is determined.

In step 704, the uplink control is sent using the determined beamdirection.

Through the above steps, the receiving end determines the beam directioncapable of being used for sending uplink control in the OFDM symbol inwhich the uplink control is located, so that the receiving end can sendthe uplink control in a range of the beam direction capable of beingused, solving problems of complicated processing existing in theconfiguration manner of locations of OFDM symbols for of uplink controlsof receiving ends in the related art, and reducing the uplink controlprocessing complexity.

In an embodiment, the step in which a beam direction used fortransmitting uplink control in the OFDM symbol in which the uplinkcontrol is located is determined may include: when signaling forinforming the receiving end of the beam direction used for transmittingthe uplink control in the OFDM symbol in which the uplink control islocated is received, determining the beam direction used fortransmitting the uplink control in the OFDM symbol in which the uplinkcontrol is located as a beam direction indicated in the receivedsignaling; or when signaling for informing the receiving end of the beamdirection used for transmitting the uplink control in the OFDM symbol inwhich the uplink control is located is not received, using by defaultall or at least one of beam directions used by the receiving end fortransmitting uplink data in the transmission unit; or when signaling forinforming the receiving end of the beam direction used for transmittingthe uplink control in the OFDM symbol in which the uplink control islocated is not received, using by default all or at least one of beamdirections used for transmitting uplink data or an uplink control in atransmission unit before the transmission unit; or when signaling forinforming the receiving end of a beam direction used for sending uplinkcontrol in the OFDM symbol in which the uplink control is located in thetransmission unit is not received, using by default all or at least oneof beam directions used for receiving downlink data in the transmissionunit.

In an embodiment, the uplink control meets at least one of: the uplinkcontrol occupying at least one OFDM symbol; the uplink control beingconfigured to send ACK/NACK information, CSI, or beam directioninformation; the uplink control being located in an OFDM symbol at anend of the transmission unit; the uplink control being located in anOFDM symbol before the OFDM symbol transmitting uplink data in thetransmission unit; or the uplink control being an area for transmittinga PUCCH, or an area for transmitting UCI.

In an embodiment, the transmission unit may be a subframe, a slot, amini slot, etc., and the OFDM symbol may be other resource unit oftime-frequency resources, which is used for characterizing a resourcemagnitude.

On the basis of the above examples and embodiments, to explain theentire process interaction of the solution, in an embodiment, an uplinkcontrol receiving method and an uplink control sending method areprovided. The methods are generally described below.

With reference to FIG. 8 , in the embodiment, when a sending end (e.g.,which may be a base station, a cell base station, a remote radio unit,etc., and is described using a base station as an example in theembodiment) configures an OFDM symbol location of uplink control (whichis described using a PUCCH as an example in the embodiment) for areceiving end (e.g., which may be a UE, a terminal, etc., and isdescribed using a UE as an example in the embodiment) in a transmissionunit (e.g., which may be a subframe, a slot, a mini slot, etc., and isdescribed using a slot as an example in the embodiment) (meaning thatmultiple OFDM symbols for sending different PUCCHs exist in the slot),an OFDM symbol for the UE to transmit data (uplink data) and an OFDMsymbol for the UE to send the PUCCH are supposed to be remainedcontinuous, so as to avoid the occurrence of a gap between the OFDMsymbol for the UE to transmit data and the OFDM symbol for the UE tosend the PUCCH when the OFDM symbol locations of the PUCCHs of the UEsare configured. Such a gap will cause additional complexity during thesending of the UE and the receiving of the base station.

When PUCCHs of multiple beam directions need to be transmitted in oneslot, uplink control with a beam direction the same as a beam directionfor sending the data in the slot is configured in an OFDM adjacent tothe data, so as to remain the sending of UE data and uplink controlcontinuous. If the base station has multiple radio frequency links,different UEs are allowed to send uplink data of multiple differentdirections in the slot at the same time. When multiple beam directionsused for transmitting the data exist in the slot, a PUCCH of the UE,which is consistent with at least one of beam directions used forsending the data in the slot, is placed in an OFDM symbol adjacent tothe data.

The uplink control described herein refers to a short PUCCH, i.e.,occupying one OFDM symbol in time domain. If subsequently the shortPUCCH is defined to occupy multiple OFDM symbols (e.g., 2, 3, etc.), themethod provided in the embodiment is still applicable.

For UEs transmitting only the PUCCHs in one slot, the locations of OFDMsymbols for these UEs to send the PUCCHs can be configured in OFDMsymbols not continuous with an OFDM symbol transmitting the data, or areconfigured correspondingly according to a beam direction used by an OFDMsymbol of each PUCCH.

The uplink control receiving method and the uplink control sendingmethod provided in the embodiment may be applied to locationconfiguration of uplink control. The methods may be generalized asfollow.

When one transmission unit includes uplink controls of differentreceiving ends and they are time-division multiplexed, when the sendingend configures an OFDM symbol location of the uplink control for thereceiving end in the transmission unit, the continuity should be keptbetween the OFMD symbol for the receiving end to send uplink data andthe OFDM symbol for the receiving end to send uplink control.

In an embodiment, the uplink control meets at least one of: uplinkcontrol of one receiving end occupying one or two OFDM symbols; theuplink control being configured to send ACK/NACK information, CSI, orbeam direction information; the uplink control being located in an OFDMsymbol at an end of the transmission unit; the uplink control beinglocated before transmitting uplink data in the transmission unit; or theuplink control being an area for transmitting a PUCCH, or an area fortransmitting UCI.

In an embodiment, keeping the continuity between the OFMD symbol for thereceiving end to send uplink data and the OFDM symbol for the receivingend to send uplink control includes: when PUCCHs of multiple beamdirections need to be transmitted in one slot, configuring uplinkcontrol with a beam direction the same as a beam direction sending thedata in the slot in an OFDM adjacent to the data, so as to remain thesending of uplink control and UE data continuous.

In an embodiment, the step in which the continuity between the OFMDsymbol for the receiving end to send uplink data and the OFDM symbol forthe receiving end to send uplink control is kept includes: if the basestation has multiple radio frequency links, allowing different UEs tosend uplink data of multiple different directions in the slot at thesame time, and when multiple beam directions used for transmitting thedata exist in the slot, configuring a PUCCH of the UE, which isconsistent with at least one of beam directions used for sending thedata in the slot, in an OFDM symbol adjacent to the data; or when a beamdirection the same as at least one of beam directions of datatransmitted in the slot exists in PUCCHs of UEs of different beamdirections, carrying, by the sending end, UCI with a beam direction thesame as at least one of beam directions transmitting uplink data in aPUCCH in an OFDM symbol immediately before or after an OFDM symboltransmitting uplink data in the slot; or when PUCCH resources ofmultiple UEs are located in different OFDM symbols in the slot,configuring, by the sending end, a PUCCH of a UE with a beam directionthe same as at least one of beam directions used for transmitting uplinkdata in the slot in a symbol adjacent to a symbol for transmittinguplink data.

The configured OFDM symbol transmitting the PUCCH is adjacent to an OFDMsymbol transmitting uplink data; or, the configured OFDM symboltransmitting the PUCCH is several (e.g., 2, 3, 4, etc.) continuous(including forward continuous or backward continuous) symbols startingfrom the symbol adjacent to uplink data transmission.

In an embodiment, the step in which the continuity between the OFMDsymbol for the receiving end to transmit uplink data and the OFDM symbolfor the receiving end to send uplink control is kept includes that: whena beam direction transmitting uplink data and a beam directiontransmitting uplink control of the same receiving end are different inone slot, the sending end configures an OFDM symbol of uplink control ofthe receiving end in an OFDM symbol adjacent to uplink data transmissionor in several continuous symbols starting from the OFDM symbol adjacentto uplink data transmission.

In an embodiment, when the sending end configures the OFDM symbollocation of the uplink control for the receiving end in the transmissionunit, a following step is included: the sending end performsconfiguration through at least one of a physical layer signaling or ahigh-layer signaling. The physical layer signaling includes downlinkcontrol information. The high-layer signaling includes an RRC message.When the physical layer signaling and the high-layer signaling are usedsimultaneously, the high-layer signaling configures a relative location(whose function is the same as the function of the foregoing presetlocation) of uplink control in the slot, including an end location ofthe slot or a location before transmitting uplink data. The physicallayer signaling configures an OFDM symbol for uplink control ofreceiving end.

In an embodiment, when the sending end configures the OFDM symbollocation of the uplink control for the receiving end in the transmissionunit, a following step is further included: the sending end implicitlycontains or configures a beam direction capable of being used forsending the uplink control in the OFDM symbol in which the uplinkcontrol is located in the slot, and sends a signaling to inform thereceiving end.

The sending end may only execute: implicitly containing or configuringthe beam direction capable of being used for sending the uplink controlin the OFDM symbol in which the uplink control is located in the slot,and sending the signaling to inform the receiving end.

In an embodiment, the implicitly containing includes that: when thesending end does not send a signaling to inform the receiving end of thebeam direction used for sending the uplink control in the OFDM symbol inwhich the uplink control is located, the sending end defaults that thereceiving end uses all or at least one of beam directions used fortransmitting uplink data in the slot; or, when the sending end does notsend signaling to inform the receiving end of the beam direction usedfor sending uplink control in the OFDM symbol in which the uplinkcontrol is located, the sending end defaults that the receiving end usesall or at least one of beam directions previously used for transmittinguplink data or an uplink control.

The uplink control receiving method and the uplink control sendingmethod of the embodiment are described below in conjunction withexamples.

It is assumed that a base station only has one radio frequency link,that is, the base station receives only one beam direction within onetime. It is assumed that UE1, UE2 and UE3 are scheduled to transmituplink data in a slot, and at this time, the UE1, UE2 and UE3 all haveuplink control to transmit in the slot. In addition, UE4 also needs totransmit uplink control in the slot. Therefore, two OFDM symbols at theend of the slot will be used for uplink control (one OFDM symbolcorresponds to one uplink control, and if each uplink control occupiestwo OFDM symbols, then four OFDM symbols at the end of the slot need tobe occupied for two uplink controls at this time. It alternatively maybe that one uplink control occupies one OFDM symbol, another uplinkcontrol occupies two OFDM symbols, and at this time, three OFDM symbolsat the end of the slot need to be occupied for two uplink controls).Beam directions of the UE1, the UE2 and the UE3 for sending uplink dataand uplink controls are consistent and consistent with each other, whichare all a beam direction 1, and a beam direction of the UE4 for sendinguplink control is a beam direction 2. Here, since the UE1, the UE2 andthe UE3 use the same beam direction to send uplink controls and uplinkdata in the slot, the uplink controls of the UE1, the UE2 and the UE3need to be configured in an OFDM symbols adjacent to transmission ofuplink data of the UE1, the UE2 and the UE3, that is, the uplinkcontrols of the UE1, the UE2 and the UE3 are configured in a penultimateOFDM symbol in the slot (transmission of uplink data of the UE1, the UE2and the UE3 terminates at an antepenultimate OFDM symbol). The uplinkcontrol of the UE4 is configured in the last OFDM symbol in the slot. Inthis way, after the UE1, UE2 and UE3 finish sending the uplink datausing the beam direction 1, the uplink controls are sent continuouslyusing the beam direction 1, avoiding the occurrence of a gap suspendingone OFDM symbol. The UE4 sends the uplink control using the beamdirection 2 in the last OFDM symbol.

In addition, if there is UE5, the UE5 only sends the uplink control inthe slot and the UE5 uses the beam direction 1. Although the UE5 doesnot send uplink data in the slot, the beam direction used by the UE5 isthe same as the beam direction of the UE1, UE2 and UE3, so that theuplink control of the UE5 is also configured in the penultimate symbolof the slot.

A simultaneous receiving ability of a base station having multiple radiofrequency links is illustrated below.

It is assumed that the base station has multiple radio frequency links,and receives eight beam directions simultaneously. It is assumed thatUE1 and UE2 are scheduled to send uplink data in a slot, and at thistime, the UE1 and UE2 both have uplink control to send in the slot. Inaddition, UE3 also needs to send uplink control in the slot. In thisway, two OFDM symbols at the end of the slot are used for uplink control(one OFDM symbol corresponds to one uplink control, and if each uplinkcontrol occupies two OFDM symbols, four OFDM symbols at the end of theslot need to be occupied for two uplink controls. It alternatively maybe that one uplink control occupies one OFDM symbol, another uplinkcontrol occupies two OFDM symbols, and at this time, three OFDM symbolsat the end of the slot need to be occupied for two uplink controls). TheUE1 sends the uplink data using the beam direction 1, and the UE2 sendsthe uplink data using the beam direction 1 and the beam direction 2 (theUE2 has two radio frequency links, and the two radio frequency linkssimultaneously send uplink data to the base station). In this way, thereare two beam directions sending data in the slot. It is assumed that theUE1 sends the uplink control using the beam direction 1, the UE2 sendsthe uplink control using the beam directions 1 and 2 (sendingsimultaneously in two beam directions in the same one ODFM symbol isbecause the UE2 has two radio frequency links), and the UE3 sends theuplink control using the beam direction 2. In this way, since the beamdirection used for uplink control of the UE1 and UE2 is the same as atleast one of beam directions sending data in the slot, the uplinkcontrols of the UE1 and UE2 are configured in an OFDM symbol adjacent todata sending of the UE1 and UE2. That is, the uplink controls of the UE1and UE2 are configured in the penultimate OFDM symbol in the slot(sending of the uplink data of the UE1 and UE2 terminates at theantepenultimate OFDM symbol). Since the beam direction used for uplinkcontrol of the UE3 is different from beam directions sending data in theslot, the uplink control of the UE3 is configured in the last OFDMsymbol in the slot. In this way, after the UE1 finishes sending theuplink data using the beam direction 1, the uplink control is sentcontinuously using the beam direction 1, avoiding the occurrence of agap suspending one OFDM symbol. After the UE2 finishes sending theuplink data using the beam directions 1 and 2, the UE2 sends the uplinkcontrol continuously using the beam directions 1 and 2, which alsoavoids the occurrence of a gap suspending one OFDM symbol. The UE3 sendsthe uplink control using the beam direction 2 in the last OFDM symbol.If the UE1 continuously uses two times of uplink control sending toincrease reliability, the UE1 may send the uplink control using the beamdirection 1 in the penultimate OFDM symbol, and then sends the uplinkcontrol using the beam direction 2 in the last OFDM symbol. At thistime, the UE1 still performs sending continuously. Since the uplinkcontrol beam direction of the UE1 is the same as at least one of uplinkdata beam directions, the configuration location of the uplink controlof the UE1 also meets the method of the embodiment, at least one time ofthe uplink controls of the UE1 is configured in a symbol adjacent touplink data.

In addition, if there is UE5, the UE5 only sends uplink control in theslot and the UE5 uses the beam direction 1. Although the UE5 does notsend uplink data in the slot, the beam direction used by the UE5 is thesame as the beam direction of the UE1 and UE2, so that the uplinkcontrol of the UE5 is also configured in the penultimate symbol of theslot.

If the uplink control is placed in the OFDM symbol before the uplinkdata in the slot, for example in FIG. 9(a), the above informationsending method of the embodiment is still suitable.

Several possible implementations are given below according to differentdescription aspects.

Implementation 1

When PUCCHs of UEs of different beam directions exist in a slot, asending end places the PUCCHs of the UEs of different beam directionsaccording to OFDM symbols, and places OFDM symbols of the PUCCHs of theUEs of different beam directions according to a following rule.

When a beam direction the same as a beam direction transmitting uplinkdata in the slot exists in the PUCCHs of the UEs of different beamdirections, the sending end places a PUCCH of a UE (e.g., UE1), whichhas a beam direction the same as the beam direction transmitting uplinkdata in the slot, in an OFDM symbol adjacent to the transmitted uplinkdata (the being adjacent herein refers to an OFDM symbol transmittinguplink data being adjacent to an OFDM symbol transmitting uplinkcontrol, and the same applies below). Corresponding to FIGS. 1 and 2 ,when the uplink control is placed at the end of the slot, the PUCCH ofthe UE1 is placed in an OFDM symbol adjacent to the OFDM symboltransmitting uplink data, or the PUCCH of the UE1 is placed backwardstarting from an OFDM symbol adjacent to the OFDM symbol transmittinguplink data. Corresponding to FIG. 9(a), when the uplink control isplaced before uplink data, the PUCCH of the UE1 is placed in an OFDMsymbol adjacent to the OFDM symbol transmitting uplink data, or thePUCCH of the UE1 is placed forward starting from an OFDM symbol adjacentto the OFDM symbol transmitting uplink data. The PUCCH of another UE(e.g., UE2) is placed before (corresponding to FIG. 9(a)) or after(corresponding to FIGS. 1 and 2 ) the PUCCH of the UE1.

The being the same includes being completely the same and being partlythe same. The being partly the same refers to that a beam directioncorresponding to the PUCCHs of the UEs of different beam directions isthe same as at least one of beam directions transmitting uplink data inthe slot. There may be multiple beam directions for transmitting uplinkdata. For example, a UE having multiple radio frequency links may senddata using two or more beam directions simultaneously, and at this time,two or more beam directions sending uplink data may occur. When the UE(which may be at least one of the UE transmitting uplink data in theslot and the other UE) sends the PUCCH, the PUCCH may be sent usingmultiple beam directions simultaneously, but at least one beam directionof the PUCCH is the same as one beam direction transmitting the data.

The basic principle is still that, in the slot, when the OFDM symbollocation of the PUCCH is configured for the UE, continuity should beremained between the OFDM symbol transmitting uplink data and the OFDMsymbol sending the PUCCH. Do not let a gap occur between the OFDM symbolof the UE for transmitting uplink data and the OFDM symbol of the UE forsending the PUCCH when the OFDM symbol location of the PUCCH of the UEis configured, since such configuration manner will cause additionalcomplexity when the UE performs the sending and the base stationperforms the receiving.

Implementation 2

When PUCCHs of UEs of different beam directions exist in a slot, asending end places the PUCCHs of the UEs of different beam directionsaccording to OFDM symbols, and places OFDM symbols of the PUCCHs of theUEs of different beam directions according to a following rule.

When a beam direction the same as at least one of beam directions ofdata transmitted in the slot exists in the PUCCHs of the UEs ofdifferent beam directions, the sending end carries UCI with a beamdirection the same as at least one of beam directions transmittinguplink data in a PUCCH in a symbol immediately before or after thesymbol transmitting uplink data in the slot.

Alternatively, when PUCCHs of multiple UEs are located in different OFDMsymbols in the slot, the base station places a PUCCH of a UE with a beamdirection the same as at least one of beam directions used fortransmitting uplink data in the slot in an OFDM symbol adjacent touplink data transmission (which also may be placed in several continuoussymbols starting from the OFDM symbol adjacent to uplink datatransmission).

Practical examples 1 and 2 are described below.

In example 1, the base station is a single radio frequency link.

Since the base station is a single radio frequency link, only uplinkdata of one beam direction is allowed to be transmitted in a slot. Inone uplink slot, the base station schedules ten UEs to transmit uplinkdata (respectively marked as UE 1 to 10), and besides PUCCHs (or UCI,and the same applies below) of the UEs 1 to 10 to be transmitted in theslot, PUCCHs of another twenty UEs (respectively marked as UE 11 to 30)also need to be transmitted. The UEs 11 to 20 transmit the PUCCHs usinga beam direction the same as the beam direction transmitting the uplinkdata in the slot, and the UEs 21 to 30 transmit the PUCCHs using a beamdirection different from the beam direction transmitting the uplink datain the slot.

It is assumed that each OFDM symbol can transmit PUCCHs of twenty UEs,and at this time, two OFDM symbols are required in this uplink slot forthe PUCCH to transmit PUCCHs of the thirty UEs. In these UEs, beamdirections of the PUCCHs of some UEs are the same as the beam directiontransmitting uplink data in the slot, and beam directions of the PUCCHsof some UEs are different from the beam direction transmitting uplinkdata in the slot. At this time, a sending end should carry the PUCCHs ofthe UEs 1 to 20 in an OFDM symbol adjacent to uplink data transmissionin the slot, and carry the PUCCHs of the UEs 21 to 30 in another OFDMsymbol.

In this way, the UEs 1 to 10 may directly continue to send their ownPUCCHs after the uplink data transmission is finished, until the PUCCHsending is finished, and then stop the sending (herein, the essence isto make the PUCCH of the UE transmitting the uplink data in the slotadjacent to the OFDM symbol of the uplink data of the UE, so that thePUCCH and the uplink data of the UE are continuously sent). The UEs 11to 20 directly send the PUCCHs in a designated symbol, and the UEs 21 to30 also directly send the PUCHHs in a designated symbol.

If location of the symbol in which the PUCCHs of the UEs 21 to 30 isexchanged with location of the symbol in which the PUCCHs of the UEs 1to 20 (carry the PUCCHs of the UEs 21 to 30 in the OFDM symbol adjacentto uplink data transmission in the slot, and carry the PUCCHs of the UEs1 to 20 in another ODFM symbol), a gap of one symbol is caused betweenthe data sending and the PUCCH sending of the UEs 1 to 20, which causesthe UE to frequently turn on and turn off the radio frequency and makesthe implementation complicated.

If it is assumed that one symbol carries PUCCHs of ten UEs at most, thePUCCHs of the UEs 1 to 10 are placed in the symbol adjacent to uplinkdata transmission in the slot, the PUCCHs of the UEs 11 to 20 are placedin an OFDM symbol adjacent to the OFDM symbol in which the PUCCHs of thefirst ten UEs are placed, and the PUCCHs of the UEs 21 to 30 are placedin an OFDM symbol adjacent to the OMFD symbol in which the PUCCHs of theUEs 11 to 20 are placed (at this time, three symbols exist in the slotto place the PUCCHs of the UEs). In this way, the essence is to placethe PUCCHs of the UEs sending uplink data in the slot into the OFDMsymbol adjacent to uplink data sending, so that this part of UEs cancontinue to send their own PUCCHs after the data sending finishes, andthe radio frequency does not need to be closed during the process,making UE implementation easy.

In example 2, on the basis of the example 1, it is assumed that a basestation has multiple radio frequency links and can receive multiple beamdirections simultaneously. At this time, uplink data transmitted in aslot can be in multiple beam directions, as long as the base station canperform receiving in the multiple beam directions simultaneously. Atthis time, in the UEs 1 to 30, if a beam direction used by the PUCCH ofa UE is the same as at least one of beam directions for the UEs 1 to 10to transmit uplink data in the slot, the PUCCH of the UE with the samebeam direction is placed in the OFDM symbol adjacent to uplink datatransmission.

Implementation 3

A base station semi-statically configures, for a UE, a location of anOFDM symbol sending a PUCCH (e.g., configuring for the UE throughhigh-layer signaling and an RRC message). For example, the base stationconfigures symbol locations of a PUCCH of a UE in a series oftransmission units (e.g., transmission units in a designated periodicinterval) for the UE (e.g., for periodical uplink control transmission),and sends configuration information to the UE. Similarly, the UEreceives the configuration information, and learns symbol locations ofits own uplink control in the series of transmission units. When theabove transmission unit is used: 1) if the UE has uplink data in thistransmission unit (the uplink data is scheduled by the base station, sothe base station knows whether the UE has uplink data in thistransmission unit), the base station adjusts by default the symbol ofthe PUCCH of the UE to be in an OFDM symbol continuous with the uplinkdata (or multiple OFDM symbols extending forward or backward startingfrom the OFDM symbol continuous with the uplink data) in thetransmission unit, and the base station will receive the uplink controlof the UE in the adjusted OFDM symbol; and 2) if the UE has uplink datain this transmission unit (the uplink data is scheduled by the basestation, so the base station knows whether the UE has uplink data inthis transmission unit), the UE adjusts by default an OFDM symbol of itsPUCCH to be in an OFDM symbol continuous with the uplink data (ormultiple OFDM symbols extending forward or backward starting from theOFDM symbol continuous with the uplink data) in the transmission unit,and the UE will send the uplink control in the adjusted OFDM symbol.

At this time, through the default dynamic adjustment of the UE and thebase station, the symbols of the uplink data and the uplink control ofthe UE in this transmission unit remain continuous.

Implementation 4

When a system is deployed in an unlicensed carrier, in one transmissionunit, a base station and a UE should keep OFDM symbols of uplink dataand uplink control of the UE continuous, so as to ensure that the UEcontinuously performs sending in this transmission unit, and a case thatthe transmission can be performed only after a use right is preempted byexecuting a mechanism of Listen Before Talk (LBT) (a rule which a devicemust perform before transmitting the data using the unlicensed carrier)additionally once is avoided, so as to ensure that the transmission isexecuted.

Therefore, when the system is deployed on the unlicensed carrier, in onetransmission unit, when (short) PUCCHs of different UEs are timedivision multiplexed, the base station and the UE should keep the OFDMsymbol transmitting the uplink data and OFDM symbol transmitting theuplink control information (sent on the PUCCH) continuous. For example,the base station keeps uplink control symbols of the UEs continuous whenconfiguring the uplink control symbols of the UE, or when the basestation and the UE have uplink data and uplink control to be sent in thetransmission unit at the same time, the symbol of uplink control of theUE and the symbol of uplink data of the UE are defaulted to becontinuous.

Implementation 5

In a case that multiple candidate PUCCH resources are configured for aUE in one slot (generally configured through high-layer signaling) andthen a specific PUCCH resource (generally configured through physicallayer signaling) is selected to be used by the UE in the slot, a basestation should configure a part of the multiple candidate PUCCHresources to be located in different OFDM symbols (one candidate PUCCHresource is one PUCCH channel). For example, at least one candidatePUCCH resource is configured to be located in a symbol continuous withan uplink data symbol (or to be continuous forward or backward startingfrom the symbol continuous with the uplink data symbol).

If in the transmission unit, the base station and the UE find that theUE simultaneously has uplink data and uplink control to be sent, thebase station and the UE use by default that candidate PUCCH resourcecontinuous with an OFDM symbol of uplink data as the specific PUCCHresource, or may also indicate the specific PUCCH resource as a certaincandidate PUCCH resource continuous with a symbol of uplink data throughsignaling.

From the perspective of the base station, when the transmission unitincludes PUCCH symbols of different UEs for time division multiplexing,when the base station configures the candidate PUCCH resources for theUE, at least one candidate PUCCH is configured within (or starting form)the symbol continuous with uplink data. When the UE has uplink data anduplink control to be sent simultaneously in the transmission unit, thebase station indicates or defaults a specific PUCCH resource of the UEin the transmission unit as a certain candidate PUCCH resource or thatcandidate PUCCH resource continuous with the uplink data symbol throughsignaling, and receives uplink control of the UE from the specific PUCCHresource.

From the perspective of the UE, the UE receives candidate PUCCH resourceconfiguration information sent by the base station and learns candidatePUCCH resources. When the UE simultaneously has uplink data and uplinkcontrol to be sent in the transmission unit, the UE receives indicationsignaling or defaults the specific PUCCH resource of the UE on thistransmission unit as a certain candidate PUCCH resource or thatcandidate PUCCH resource continuous with the uplink data symbol, andsends the uplink control of the UE via the specific PUCCH resource.

Implementation 6

This implementation provides a beam direction determination method whenuplink control is sent, so that a receiving end (e.g., a UE) can use acorrect beam direction to send uplink control in an allocated uplinkcontrol resource; and a sending end (e.g., a base station) alsocorrespondingly uses a correct beam direction for reception.

The base station configures beam directions, allowed to be used, of OFDMsymbols in which different PUCCHs are located in a slot, and sends thisconfiguration information to the UE. The base station uses acorresponding beam direction to perform receiving in the OFDM symbol inwhich the PUCCH is located.

For example, two short PUCCHs are respectively located two OFDM symbolsin the end (which may also be before the uplink data) of the slot, thebase station can configure the last OFDM symbol to use the beamdirection 1 (herein, which may be multiple beam directions, and ifmultiple beam directions are used, the base station needs tosimultaneously have multiple radio frequency links to performreceiving), and configures the penultimate OFDM symbol to use the beamdirection 2. Then, the base station sends configuration signaling to theUE. For example, it may be sent using semi-static high-layer signaling,so that the configuration information is valid for a long time. It mayalso be sent through physical layer signaling, so that the configurationinformation can be dynamically changed and adjusted.

The UE receives the configuration sent by the base station, learns thebeam direction capable of being used by the OFDM symbol of each PUCCH inthe slot, and after the UE is configured with an OFDM symbol location ofthe PUCCH, sends uplink control to the base station using a beamdirection used by the OFDM symbol.

For the same OFDM symbol, the UE may use the beam direction 1 to performsending, but the base station may use the beam direction 1 or the beamdirection 2 to perform receiving. The beam direction of the OFDM symbolin which the PUCCH is located sent by the base station to the UE isdefined at a UE side, and the beam direction used by the base station toreceive a PUCCH of a certain OFDM symbol is defined at the base stationside.

Implementation 7

Another solution is given based on the implementation 6.

The base station configures beam directions, allowed to be used, of OFDMsymbols in which different PUCCHs are located in the slot, and sendsthis configuration information to the UE. The base station uses acorresponding beam direction to perform receiving in the OFDM symbol inwhich the PUCCH is located.

For example, two short PUCCHs are respectively located at two OFDMsymbols (which may also be before the uplink data) in the end of theslot, the base station configures its uplink control on the last OFDMsymbol for the UE1, and uses the beam direction 1 (herein, which may bemultiple beam directions, and if multiple beam directions are used, thebase station needs to simultaneously have multiple radio frequency linksto perform receiving), and configures its uplink control on thepenultimate OFDM symbol for the UE2 and uses the beam direction 2. Then,the base station sends configuration signaling to the UE1 and the UE2.For example, it may be sent using semi-static high-layer signaling, sothat the configuration information is valid for a long time. It may alsobe sent through physical layer signaling, so that the configurationinformation can be dynamically changed and adjusted.

The UE1 and the UE2 respectively receive the configuration informationsent by the base station, and learn their uplink control symbollocations and the used beam directions. The UE1 and the UE2 respectivelysend uplink control to the base station using the configured beamdirections in the configured OFDM symbol locations.

For the same OFDM symbol, the UE may use the beam direction 1 to performsending, but the base station may use the beam direction 1 or the beamdirection 2 to perform receiving. The beam direction of the OFDM symbolin which the PUCCH is located sent by the base station to the UE isdefined at the UE side, and the beam direction used by the base stationto receive a PUCCH of a certain OFDM symbol is defined at the basestation side.

Implementation 8

This embodiment provides a resource allocation method, so as to adapt tothe use of high-band beams.

When a base station configures multiple candidate resources for a UE,the multiple candidate resources may be located in OFDM symbols(hereinafter, symbols) of different beam directions, so that whenindicating a candidate resource used by the UE, according to beamdirection requirement, one candidate resource can be selected as theresource used by the UE from the candidate resources corresponding to abeam direction meeting the requirement.

For example, with reference to FIG. 9(b), multiple channel resources(e.g., PUCCH channels) exist in one slot (or one subframe, etc.), and itis assumed herein that each channel resource occupies one OFDM symbol(the principle is the same when each channel resource occupies othernumbers of OFDM symbols). For example, in two OFDM symbols at the end ofa slot, each symbol has one PUCCH channel, and corresponds to a certainbeam direction (alternatively, the two symbols may correspond to thesame beam direction). For example, the last symbol corresponds to thebeam direction 1, and the penultimate symbol corresponds to the beamdirection 2. When the base station configures multiple candidateresources for the UE, the base station may configure a part of candidateresources in the last symbol, corresponding to the beam direction 1,configures a part of candidate resources in the penultimate symbol,corresponding to the beam direction 2, and sends configurationinformation to the UE (including symbol locations and beam directions ofthe candidate resources). In the use, the base station selects asuitable candidate resource as a used resource for the UE according tothe beam direction of uplink control or uplink data of the UE in thecurrent slot. For example, when the UE needs to use the beam direction 1in this slot, the base station indicates one of candidate resources inthe last symbol as the resource used by the UE. In another example, whenthe UE needs to use the beam direction 2 in this slot, the base stationindicates one of candidate resources in the penultimate symbol as theresource used by the UE.

The UE receives signaling sent by the base station, learning informationof the used resource (from multiple candidate resources) and acorresponding symbol location as well as a beam direction, and thensends uplink data using the corresponding beam direction in the usedresource.

In this way, since multiple candidate resources are located in symbolsof different beam directions, it is helpful for the base station toselect the suitable candidate resource as the used resource according tothe beam direction requirement of the UE to transmit data. If the basestation configures multiple candidate resources in symbols with the samebeam direction, the UE cannot obtain used resources of other beamdirections when the UE needs these used resources, since the basestation does not configure candidate resources of other beam directions.

Implementation 9

A method for indicating an uplink control time domain location isprovided in this example. This method has small signaling overhead.

If one UE transmits both uplink data (such as a PUSCH) and uplinkcontrol (such as a PUCCH) in a certain slot simultaneously, a basestation only indicates an OFDM symbol location of the uplink control ofthe UE for the UE according to a following rule.

The base station uses dedicated downlink control information (DCI) toindicate the symbol location of the uplink control to a scheduled UE. Aslot location does not require a clear signaling indication (thus savingsignaling), but a slot location in which a symbol location of uplinkcontrol indicated by the base station by default is located is a slot inwhich the uplink data of the UE is located. The DCI is DCI correspondingto uplink grant information of the UE. The UE receives DCI correspondingto uplink data scheduling, and determines the symbol location of theuplink control. At the same time, the UE defaults that the slot locationin which the symbol location of the uplink control is located is theslot in which uplink data of the UE is located.
